Engineering specific study

This thesis presents a study of impedance optimisation of active microstrip patch antennas to multiple frequency points. A single layered aperture coupled microstrip patch antenna has been optimised to match the source reflection coefficient of a transistor in designing an active antenna. The active aperture coupled microstrip patch antenna was optimised to satisfy Global Positioning System (GPS) frequency specifications.

The Australian music industry is growing and developing yet specific information about the ways in which distribution systems develop is limited. In this study I examined the growth and change of the Australian music value chain. This includes the development of digital distribution systems and the effect that peer‐to‐peer technology has on system development, specifically the disintermediation between consumers and artists to the detriment of the multinational value chains.
